What temperature is considered a fever

Generally speaking, fever refers to an elevated body temperature. The determination of what constitutes a fever depends on the site of measurement. If the temperature is measured under the armpit, a body temperature exceeding 37°C is generally considered a fever. If measured orally, a temperature above 37.3°C is typically considered a fever. If measured rectally, the threshold for fever is relatively higher, and a temperature exceeding 37.7°C is considered a fever. A temperature above 41°C is classified as hyperpyrexia (extremely high fever). Detailed explanations are as follows:

If the temperature is measured under the armpit, a body temperature exceeding 37°C is generally considered a fever, and above 41°C is classified as hyperpyrexia. It is recommended to seek timely medical attention and, under a doctor's guidance, use medications such as ibuprofen tablets, acetaminophen tablets, or Lianhua Qingwen capsules to relieve symptoms.

If the temperature is measured orally, a temperature above 37.3°C is generally considered a fever, and above 41°C is classified as hyperpyrexia. When placing the thermometer inside the mouth for measurement, it is recommended to maintain the correct posture to ensure good contact between the thermometer and the oral cavity for accurate readings.

If the temperature is measured rectally, since rectal temperature is closer to the body's core temperature, the fever threshold is relatively higher. A temperature above 37.7°C is considered a fever, and above 41°C is classified as hyperpyrexia.

It is recommended that patients with fever ensure adequate rest in daily life, maintain local hygiene, and avoid consuming irritating foods to prevent worsening of the condition.
